SU115192A1 - Gas burner for baking and confectionery ovens - Google Patents

Description

The invention relates to gas for baking and confectionery ovens using a mixing chamber, a distribution pipe with several rows of outlets and a ceramic nozzle.

According to the invention, the use of a gas burner allows an increase in the degree of combustion of the gas mixture.

The essence of the proposal is that the ceramic nozzle of a gas burner is made in the form of two parallel-installed slatted blocks, mounted on both sides along the outlet openings of the distribution pipe; The blocks have internal inclined walls heated by the flame of the combusted gas mixture, which form a wedge-shaped gap between them, in which the unburned gas mixture is left unburned upon leaving the distribution pipe.

FIG. 1 shows a view of the gas with a partial cut; in fig. 2- cross section of two versions of the burner.

The gas burner (Fig. 1) contains a mixing chamber / where the gas-air mixture is prepared, a distribution pipe 2 with several rows of outlets 5 and a ceramic nozzle 4.

The ceramic nozzle is made in the form of slatted blocks 5 installed on both sides of the combustion front for the entire length of the working part of the burner. Blocks 5 have heated flames. burned gas mixture, internal inclined walls 6, forming a wedge-shaped gap between them, in which the unburned gas mixture is burned unburned on leaving the distribution pipe 2.

One row of outlet openings 5 of the distribution pipe 2 comes under the shaped ledge of one of the blocks, and the flame from these openings quickly heats the ceramic nozzle.

FIG. 2 shows two more embodiments of the proposed burner. Here is a burner in which both rows of its holes 3

located under the protrusions in the blocks 5 and form streams of the flame 7, as well as the burner, which, in addition to the rows of holes 5 located under the projections of the blocks 5, has another row of holes 8 for the main flow of the flame 9.

Gas burner is designed for baking and confectionery ovens. It can work both in baking chambers with high relative humidity (80-90Vo), and in channels with an environment of flue gases and a low ambient temperature — gases and surfaces.

The burner can also be used in other areas of the industry where it is necessary to burn gas in an environment of gases inert for combustion with a low temperature of this medium and a low temperature of surrounding surfaces, as well as where there is a need to burn gas in an environment with high relative humidity.

Subject invention

Gas burner for baking and confectionery ovens using a mixing chamber, a distribution pipe with several rows of outlets and a ceramic nozzle, characterized in that, in order to increase the degree of combustion of the gas mixture, its ceramic nozzle is made in the form of two parallel planed blocks mounted on both sides along the outlet openings of the distribution pipe and having internal inclined walls heated by the flame of the combusted gas mixture, forming between them the Kli a uniform gap in which the gas mixture unburned as it leaves the distribution pipe is burned.
